To all whom it may concern:

Be it known that I, JOHN H. BAisDnN, Jr., a. citizen of the UnitedStates, residing at Chattaroy, in the county of Mingo and State of \VestVirginizu have invented certain new and useful Improvements inCar-Dun'iping Mechanisms, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to certain new and useful improvements inautomatically operated car dumping mechanism and has for its object toprovide a comparatively simple mechanism. of the above character whichis adapted to be actuated by the cars to automatically release andremove an empty car from the rails of the track section by the movementof a loaded car thereon.

Another object resides in the arrangement of the car supporting meansbetween the rails of the track section, said means comprisingtransversely movable shoes adapted to be positioned against the fronttruck wheels of the car to support the same in position to be dumped,said shoes being cooperatively connected with pivotally mountedlongitudinally disposed bars adapted to be engaged by the truck wheelsof a loaded car to release the empty car after the same has been dumped.

W ith these and other objects in view, the invention consists of thenovel construction, combination and arrangement of parts hereinafterfully described and claimed, and illustrated in the accompanyingdrawing, in which- Figure 1 is a side elevation showing the pivotallymounted track section and an empty and loaded car positioned thereon;Fig. 2 is a top plan view of the track section showing the operatingmechanism; Fig. 3 is a section taken on the line 33 of Fig. 2; Fig. 4.is a section taken on the line as of Fig. 2; Fig. 5 is a view similar toFig. 4 showing the car holding shoes in open position; Fig. (3 is asection similar to Fig. 3 showing the position of the parts when theshoes are open; Fig. 7 is a detail perspective view of one of themovable shoes and the reciprocatory rack bar connected thereto. Fig. 8is a section taken on the line 8-8 of 2; Fig. 9 is a detail perspectiveView of one of the releasing plates.

Referring more particularly to the drawings 5 indicates a track sectionwhich may be supported upon any suitable frame structure and is mountedat one side of its longitudinal center upon a transversely positionedaxle 6. The track rails 7 form a continuation of an ordinary car track 8when the section 5 is in its normal position as shown in Fig. 1. Theforward end of the pivotally supported track section 5 extends outwardlyover the car. Built against one side of the frame immediately beneaththe track section is a framework B which is adapted to limit thedownward movement of the forward end of the track section when the caris disposed in dumping position upon the rails. This inclination of thetrack sections is approximately n at which inclination the entirecontents of the car will be emptied into the dumping pit or conveyingcars upon which the coal or other material is being loaded. The deviceis well adapted for the latter purpose as it obviates the necessity offrequent handling of the coal, the same being conveyed directly from themine upon the tilting track section and there dumped into the cars in amanner which will now be set forth in detail.

Extending transversely between the rails 7 there is a channel bar 9.This channel bar is formed upon its ends with the laterally eX- tendingflange 10 by means of which the same is rigidly secured to the webs ofthe rails as by the bolts 11 clearly shown in Fig. 2 of the drawing. Oneend of a longitudinally extending rock shaft 12 is journaled in abearing 13 centrally secured upon the upper edge of one of the parallellongitudinal flanges 10 of the channel bar 9. This rock shaft extendsrearwardly between the rails of the track sections and is actuated bysuitable releasing means to be hereinafter described. Upon the forwardend of the shaft 12 a segmental gear 13 is secured. This gear engageswith the teeth 15 formed upon the surface of a reciprocatory rack bar14. This rack bar also has the teeth 16 formed upon its inner edge whichmesh with the teeth of the pinion 17 pivot-ally arranged centrally uponthe base of the channel bar 10. A second rack bar 18 which is likewiseadapted to have reciprocatory movement. between the flanges of thechannel bar is also provided with teeth 18 upon its inner edge formeshing engagement with the teeth of the pinion 17. The opposite ends ofrack bars 14L and 18 are angularly extended inwardly from the opposedflanges of the channel bar as shown at 19 and have their extremitiesarranged in the bifurcated inner ends of the rods 20. The ends of therack bars are loosely connected to the ends of the rods 20 by means ofthe bolts 21. The outer ends of the bolts 21 are disposed through arectangular opening 22 formed in each of the rails 7 of the tracksection. ilpon the ends of the rods 20 the shoes 23 are secured the endsof said rods being threaded to re ceive the nuts 24 to secure the shoesthereon. The head and outer flange of each of the rails is cut away orrecessed as shown at 25 to receive the shoe 23, said shoe being adaptedto fit closely upon the rail when engaged with the truck wheels as shownin Fig. 1. The inner ends of each of the rack bars have one end of aretractile spring 42 connected thereto, the other end of each of saidsprings being secured in any suitable manner to the web of the rail.These springs are adapted to retain the shoes normally in engagementupon the track rails. The base of the channel bar 9 is extended beyondthe rails to form a support 26 for the shoes when they are movedoutwardly from the rails to release the car. A guide flange 27 is formedupon one edge of the supporting plate and has its inner edge laterallyextended as shown at 28 and is secured upon the outer face of the railweb by means of one of the attaching bolts 11. It will be noted fromreference to Fig. 4 that the outer ends of the rack bars 14: and 18 areinclined upwardly as well as inwardly. In order to extend the outer endsof the rods 20 through the rails it is therefore necessary to bend thesame as shown at 20. Thus as the rack bars are reciprocated in oppositedirections and the shoes 23 moved outwardly and downwardly upon thesupporting plates 26, the rods 20 will move freely through therectangular openings 22 in the rails without danger of binding againstthe edges thereof.

The rear ends of the rails 7 of the track section are connected andbraced apart by the parallel bars 29. A bearing plate 30 is centrallysecured to one of the bars of each of said braces to receive the rearend of the central longitudinally extending rock shaft 12. Spaced pairsof L-shaped bracket plates 31 are secured to each of the rails 7 andproject outwardly therefrom. Between these plates the link bars 32 arepivotally disposed and have secured to their upper ends the releasingplates 33. These plates are longitudinally positioned in parallelrelation to the track rails and as shown in Fig. 2 have their rear endsoutwardly curved as at 33' for the engagement of the truck wheelsthereagainst in the operation of the releasing mechanism. The majorportions of the link bars 32 depend below the track rails upon one sideof the movable track section and are adjust-ably connected to thebifurcated outer ends of the substantially Z-shaped link rods or bars34. The upper inner ends of these bars extend between the transverselyarranged brace bars 29 and have their extrem ities bifurcated to receivethe ends of the connecting links 35. These links are pivotally mountedbetween the depending plates 36 secured to the brace bars 30 and havetheir lower ends connected to similar links 37. The lower ends of thebars 32 mounted upon the other of the track rails have connected theretoone end of the inwardly extending bars 38 the inner ends of which arepivotally connected to the links 37. The rock shaft 12 is adapted to beactuated through the medium of the connecting links 39, the upper endsof which are rigidly secured to said shaft and have their lower endsadjustably connected to the inner ends of the bars 38.

In the operation of the device, the loaded car 40 moves upon the tiltingtrack section and the forward truck wheels il thereof are engaged by theupper curved surfaces 23 of the shoes 23. When in this position thegreater portion of the weight of the car will be disposed forwardly ofthe supporting axle (3, and the entire track section and the car will betilted to an angle of substantially 45 over the dump or transporting carinto which the coal to be deposited. The ordinary coal car as used inthe mines is of comparatively light construc tion, and after the coalhas been released 'tl erefrom the weight of said car will beoverbalanced by the distribution of the weight of the track rails, therearwardly extending portion of the rails rcturning the car to itsnormal position. The car is now supported upon the rails of the movablesection and prevented from forward movement by the shoes 23. This car isreleased and projected for 'ardly upon the stationary track by the nextloaded car which enters the tilting or dumping track section. Upon theentrance of this second car on the dumping rails, the forward truckwheels will engage with the outwardly curved end portions of thereleasing plates and move or spread the same apart, said plates beingnormally disposed with their lower edges above the inner edge of therail heads. Thus when these plates are engaged with the trncl: wheelsthere will be considerable outward movement of the same, which movementthrough the link connections between the bars 32 and the depending bars39 rigidly connected to the rock shaft 12, will reciprocate the rackbars 1st and 18 in opposite directions and move the holding shoes 23outwardly or away from the rails 7. Thus the truck wheels of the forwardcar are released and at the name time the rear of said car is struck bythe loaded ear with sufficient force to move the empty car the requireddistance to dispose the same upon the stationary track before the truckwheels of the loaded car have passed from between the releasing plates33. When the empty car has thus been released the retractile spring 42will return the holding shoes s3 to their normal position to engage withthe truck wheels of the loaded car to hold the same while it is beingdumped as previously described. Thus it will be seen that the cars maybe automatically dumped, eliminating the necessity of the frequentrehandling of the coal in its removal from the mine to the transportingcars. No manual labor is required beyond the initial loading of the coalears, the pcnse incident to the handling of the coal in the manner atpresent in vogue being entirely overcome.

From the foregoing it is believed that the operation and many advantagesto be attained by the use of my improved dumping mechanism will bereadily apparent without requiring a more extended description.

The device is comparatively simple, has no delicate parts involved inits construction and is very positive in its operation.

The cost of installing the mechanism is comparatively small and it isalso highly effieient and very durable in operation.

\Vhile I have shown and described what I believe to be the preferredembodiment of my invention it will be understood that the same issusceptible of numerous minor modifications without materially departingfrom the essential features or sacrificing any of the advantagesthereof.
